Play Frog Grog for Free

When you think of slot machine themes, frogs aren't usually the first things that spring to mind. However, among all of the pharaohs and pirates, there is a surprisingly large amount of gambling games out their that call on the slimy little amphibians for inspiration. After all, the frog is a staple ingredient of many a fairytale, or a witch's stew for that matter. Frog Grog belongs to the latter style of game, presenting a sorcerer's cabinet of potions and other vital ingredients for a good cauldron brew – we're talking about glowing moths and prickly thistles. As such, players are invited to spin the reels, with each successful combination of matching potions offering a prize payout.

The value of the payout in this slot machine depends on how much a punter places as a total bet and on how many symbols are aligned. There are 23 paylines in total, and players can opt to place anywhere from 0.10 to 100.00 game credits as a wager on all paylines. With the bets in place and the reels in motion, spinners can hope to come across the prizes represented in the table below as total bet multiplier values:

From the looks of that paytable, this slot machine isn't going to provide the biggest wins in the world of online slots. However, that is far from being the case, as players of the game will soon realise.

One of the games primary gameplay elements is a “Dropping Symbols” feature. This basically means that every time in which a winning combination is struck, the icons in question will be replaced by new random symbols, creating the chance for another win to be struck. Every time that a new win is created, the multiplier scale at the side of the reel is advanced, from x1 on the first win to x7 on the fifth consecutive win. So, if you are lucky enough to line up a number of wins in a row, you could see those wins leapfrog into some high jackpot territory.

Another way in which this slot machine helps players to boost their winnings is with the special wild frog symbol. First of all, this icon substitutes for all others in the paytable, effectively helping to fill in the gaps for winning combinations. What's more, when this froggy symbol appears it will give a big belch. OK, so that might not sound particularly pleasant, but it will cause all of the icons in the frog's row and column to be erased, allowing for new symbols to drop in and new potential wins to be had.

It would seem that this froggy slot machine has more tricks up its sleeves than first meets the eye. And it gets better. That is because there is a special “Mystery Game” feature in which players have the chance to increase their prize-haul. The game is triggered completely at random after all symbols have dropped, removing all of the icons on the reels except for the moth, thistle and the wild frog. All of the removed icons will award wins in accordance to the paytable up to a maximum equivalent of 5-in-a-row.

Frog Grog is one of the stranger slot machines to have come out of Thunderkick's design studio in recent times. And that is saying something for a company that has made games like Esqueleto Explosivo, The Rift and Arcader. The plus side is that “strange” usually equates to “exciting” in the world of slot machines, because it is always enjoyable to try out different themes and newfangled gameplay styles. Frog Grog has both of those things in abundance.
